Re: [Veritas-bu] Whats Best Practice for SSO in NBU 5.1

I agree with Randy, I've had a lot of issues with the Media/SAN Media Windows servers. I would recommend that if you are pre 6.x, examine your backup requirements for each server and use teaming (I have also experienced problems with these) or Gig NICs when you can. Not only will this solution save you money, but it will also save you administration headache, regardless of Media server platform, when you do run into problems.

NetBackup doesn't "get it" until version 6. I am 100% windows here with a mixture of 19 Media and SAN Media servers sharing a library with 24 drives. First, stabilize it. Zone your library and make sure that the only servers that can even see the library are servers that you want to see the library. Check HBA settings and disable removable storage service. Until you have the communication paths really stable between servers and drives, the problems won’t ever cease. But once you have it stable, it typically will stay that way.

However, in version 5.1, whenever I had to do any type of maintenance on my library causing it to lose connection to NetBackup servers, I had to reboot all of my NetBackup servers before I could get NetBackup to see the library again. My SAN Media servers are high profile servers and rebooting them periodically wasn’t a popular activity with our customers. Microsoft said it wasn’t Windows, Symantec said it wasn’t NetBackup and I could never get a straight answer. But 6.0 doesn’t have that problem. I can reboot the library all day long and as soon as it is back on line, NetBackup is back on line.

Thanks,

Randy

but would you implement such a large sso environment with Windows servers? we've shared 20,30,40 drives across many windows servers and it becomes hell whenever drives go offline and/or is replaced and then shuffles in the os. we've used persistent binding but this doesn't help with vtl drives. but sometimes, netbackup just doesn't get it.
